In the series premiere, Gary, Chris and Matt are faced with two challenges: first, a Big Lobster, and second, trying not to offend Australians too much.

We're going highbrow this week. Or at least, we're trying to. It all falls apart when Matt suggests some unusual toast preferences.

This week: we get stuck somewhere dark, it all gets a bit serious for a moment, and Gary pulls his hoodie over his head. It's all kicking off.

This week... well, there's more than one type of toilet humour in here. Brace yourselves, folks: 'cos we're goin' lowbrow.

As the sun sets, we have an entire pastry-based episode, offend the Dutch, and have a nun pun run.

Dusk has fallen, and while we start off with science fiction farce and retro British TV, it all goes a bit dark when we starting talking about armageddon.

This week, Gary works on his impressions, we delve into some European history, and Chris pops a button.

This week, we get distracted by chocolate, disrespect a man who's been dead for nearly a century, and debate low-gravity football.

It's the season finale! As the sun sets, we talk about very cold sports; Tom learns he's got weak fingers; and surprisingly, it all ends on a song.

We're back! We start with the tale of Thomas Trueblood, rapidly steer off into the 1904 Olympic marathon -- perhaps the most ridiculous Olympic race ever -- and then have a quick discussion about a man called Jam Handy. Get your mystery biscuits ready.

This week, we start with Steve Irwin, discuss some shocking fish, and tell a tale of a penguin in the desert who just needed a hug.

Highbrow and lowbrow collide this week, as a giant brass arse meets Thomas Pynchon. And there's a barnstorming start from Matt as he connects "Livermore, California" with a rather famous bulb.

This week, interstellar spammers meet Ming the Merciless. And folks outside the UK might want to have a Google window open, because we're about to crack through a whole load of musical references that never made it outside our borders.

This week, we delve into obscure British traditions, and Gary gets points for two of his specialist subjects: archives and goose impressions.

This week, we're meant to be talking about a not-so-famous adventurer, but it rapidly runs into deep-fried food and a baking disaster.

It's the last episode of the season! This time we're talking about Michael Caine: COVERED IN BEES. Thanks for watching this run, everyone: we'll be back in the summe

We're back again! We start with the tale of SS Bessemer, but soon enough we're coming up with a rejected Bond villain, working out how schooling really happens in Rotherham, and then inventing a terrible butler. Hold on to your mystery biscuits, because this is Citation Needed, Season 3.

It turns out the Citation Needed team have a certain amount of skepticism when it comes to mythological beasties. So rather than talk about the boobrie, it's on to slaughtering birds, extinct creatures, and why all pandas are actually Conservatives.

Surprisingly few tangents this week, because the subject matter is astonishing enough that there's no stopping us. Apart from getting a cat stuck in an index file, of course.

This week! We're tracking down some suggestive pseudoscience, and wondering about the Queen's package. And no, you're not finding out what was in the bit that got removed for legal reasons.

Last in this season! We take on a former President of the USA, and one particularly vicious rabbit. Thanks for watching, everyone!

We're back! And back where we belong, too, in a kitchen with dodgy lighting. Time for a new run of five episodes, and our not-so-new problem with slightly insulting the nations of Europe. This time, to the Mediterranean, and to Graham Island.

We're off to the Left Bit of Bottom America (thanks Matt), to Chile, and to a socialist scheme to bring a computer revolution decades early. Just one problem: people.

This week, we're taking on the world of medicine as we run through dodgy research, quack cures, and homeopathic kitten chlamydia.

From East Asia to West Yorkshire, today we're taking on the world's culinary delights and some odd governmental manipulations.

Last in this season! Today we're off to France for a tale of the world's greatest conman, the Eiffel Tower, and some easy points.

We're back! Good luck to everyone who's subscribed since the last season, heaven knows what you'll think of it. This time, we're talking about ancient technology, Morse code, and taking a brief diversion into Latin!

This week, we're stopping at taking on one of the most -- and least -- successful inventors in history, travelling via a television flop and a brief diversion into stained glass!

This week, a business venture that never got off the ground, and one of Gary's regular diversions into TRAINS.

I think if we've learned anything from this episode, it's that Tom would probably not have survived Chris' childhood.

Last in this season! Yes, we've talked about psychics and pseudoscience before, but this time there's a very different approach behind it…

We're back! And we start Season 6 with a tale of bravery, bagpipes, and big Scottish swords - with a live studio audience.

Today, we're not delving into history: instead we're talking about language, pop culture, and one heck of a sandwich.

Please welcome our guest panelist Will Seaward, as we run through ecological disasters and unintended consequences!

In this episode: four men from England, talking about a woman from France. Nothing can possibly go wrong.

"That is horrific," says Matt at one point during this episode. He's not wrong. We delve into unconventional Cold War tactics, and some surprising - and doomed - members of the animal kingdom.

In the season finale: Gary gets nauseous, Matt gets accused of being a minor royal, and Chris pulls a face. This time, we're back at the founding of America, talking about a man who helped, or perhaps hindered, a famous expedition...

Back in front of a live studio audience! We start off Season 7 with a tale of bravery, courage, and omelettes.

This week, Gary's on home turf, Matt's hoping to float on air, and we all set a new record for longest time to get to the actual subject of the article.

Matt Parker joins the team this week, in which there's talk of the great cream seams and a surprisingly in-depth discussion of how quadrupeds might juggle.

In the second of two shows with guest Matt Parker, we're covering some hair-raising history, and also imagining some little ears flapping in the breeze.

This time, join us for a tale of politics, intrigue, and a man dropping his trousers.

It's the last show of the season, and we're going out with a bang.

The final season begins! With a traditional tale of a military mistake and a wheel that spins and lands on France.

This time, we're taking on smørpanikk, food politics, and - for the second week running - brandy.

Our traditional Wartime Badass Episode this week, albeit a wartime badass whose weapon included expense reports.

No, a hail cannon isn't for if you just want to accelerate a lot of hail really quickly. This week: pseudoscience and real science!

I realise we never actually define "pumpy thing" in this video. I'm not going to define it here either.

That's it! That's the end of the series. You made it! Congratulations! Enjoy the best mime that Matt has ever done.
